Hydrostatic indifference plane

from Wikipedia, the free encyclopedia

The term hydrostatic level of indifference is used in human physiology . It refers to the point in the human body where the blood pressure is identical both when standing and when lying down.

When lying down, the blood pressure is about the same in all arteries . The same goes for the veins of the body. If the person stands up, the blood pressure rises in the lower half of the body due to the weight of the blood, whereas the blood pressure drops in the upper half of the body. It remains constant in the hydrostatic indifference plane, about 5–10 cm below the diaphragm .
